Thank you everyone for all your help and tips on the strange issue we had! You guys are awesome!
May I suggest for your city location that you add some dew shields to the end of the main scope and the guide scope. Stray light can reflect off some surfaces and cause artifacts and gradients. Keeping your lenses and mirrors more in the dark could only help. Thanks for sharing and congrats on your new home!
Thanks John and that is a very smart suggestion.
Awesome Job! I had the pleasure to work with an image that was taken with a Triad. Very Impressed with it.
Looking forward to more "backyard " images!
Thanks for this video,I've been thinking about buying this filter.Now I will.
Great video! I identified myself so much with the part in which you said "Good morning!" to the telescope, after leaving it capturing images all night. Having a backyard is a bless!.
Thanks! And yes, it's so nice!!
I'm getting a sky watcher Eq5 mount tomorrow...... So excited. Love your videos!
Well, this filter really does a great job. Got me quite interested😊
Thanks to both of you for sharing.
Clear skies 🤘🤘🤘
Thanks, and yes we were pretty impressed with it!
Looks very good!
Thanks Chuck!! So happy to be part of the "backyard astrophotographers" now too :)
@@GalacticHunter Congrats!
Now I just need Trevor to show up, then all my “astroinspirators” are present in the same “room” 👍😊
Cool video. I love when you guys do experiments. So much more can be shared by these type of videos rather than the “look what I can do” b-rolls that flood UA-cam. I know you’re happy you don’t have to drive miles. Congratulations on the new place. Clear skies.
Thank you Garnett!
I have been wanting to try one of these.
I have a 1600MC pro cooled which, thankfully, doesn't have any dew issues. I use this in conjuction with an optolong L Pro filter. It does a reasonable job in Bortle 5. My friend has a narrowband setup which is MASSIVE ballache.. Each filter requires a slight refocus, each filter requires a minimum of 2 hours on a typical target, then almost a whole day of stressful processing... I was always expecting my OSC to be a stepping stone to NB. Now, after seeing your results and considering my friend's woes I might just take the plunge... This filter seems to get some of the NB benefits from OSC.... Whilst I appreciate that one has little control over the colour from each emmision line, I would be interested to see how it performs on more colourful subjects
Yes, sadly galaxy season is about to start but we wish we were able to use it on more nebulae :/
Beautiful work!
Thank you!
Amazing!
Great image!💫
Great before/after comparison. Had no idea this filter cost that much. But the difference it made was remarkable. I concur with others that the initial images were affected by ice/condensation on the camera sensor. Even though your humidity is low, rapid, deep cooling will cause even minute amounts of moisture to condense then freeze.
Love your videos and the quality of the images keeps getting better and better.
Thank you so much!
Great picture 👍
Now you can start thinking about cable management and save even more time setting up.
Clear skies!
Thanks! And yes we definitely need to tidy up these cables and manage them better :)
Awesome job.
Thanks!
Great stuff , nice eh imaging from home , and no more getting bothered by creepy crawlies !
Haha we're probably still going to image from the desert most of the time as you can't beat dark skies, but we're glad we now have the option of also staying at home :)
The “creepy crawlers” with 2 legs are the kind I worry about when at a remote site. But that’s where the sky is darker and bigger.
Looks like ice on the sensor itself. I have the ASI071MC Pro as well and have had exactly the same thing, especially when taking the camera from a warm environment (house) to cold (back yard) and then cooling quite rapidly. I have solved by removing the desiccant tablets and heating in a microwave to dry them out before replacing while still warm. I have also found that the ASIAir cools the camera too rapidly and so tend to do this manually in a couple of steps. When using other software such as APT or NINA to control the camera, the cooling routines there cool much slower over 10 - 15 minutes and this seems to work much better and doesn't lead to ice. When I have had ice before I have warmed back up to +5°C, held there for a couple of minutes, and then re-cooled in 5°C steps back to the -10°C that I usually run at. Hope this helps.
Thanks Daniel, another person said almost the similar thing so that must definitely be the issue. We'll see if it happens again and if so, will follow you guys' advice :)
Try to dry the air inside the CMOS Chamber with the screw in dryer cartridge. For my QHY it is a aluminium cylinder with a thread that can be filled with silica gel.
I have the same polar alignment issues. I can see the roof in the polar scope also!
Haha we got pretty lucky there. Wasn't sure we would be able to see Polaris when we moved in.
I got an optolong L-eXtreme Filter, works great
@galactic hunter every day i wish i have a good night of astronamy
Same!
I don’t know your system but this past winter at 8,000’ in New Mexico (where the humidity is low) I found my guiding was decreasing in quality one night, also the imaging began to develop a haze . I went to check the two scopes and both had the first hints of frost appearing on then. In addition to humidity one needs to be aware of falling temperatures. So it’s good to know the dew-point for night in addition to humidity to help anticipate whether dew or frost may be an issue. My cmos and dslr cameras are sealed enough that I think OTA dew is a problem first, but I don’t know your equipment. This is just a thought.
Nice videos
Good morning and happy New Years. I have a question. Yesterday I ordered the Radian Triad Ultra filter for fast telescopes. My telescope is a F4 instrument. Is this filter the right chose? Or does the filter only work with fast telescopes that are F3 and below? Thanks
Nice filter, nice pics, a bit spendy. Looks like road trips to local ski hill is still my best answer. P.s nice setup.
Wow nice is this filter available for mirrorless Eos R system ?
Nice result in the end! Did you find out what was the problem that caused the artifacts? I am wondering if -20 degrees was too much and it could have been the reason for those artifacts. I am interested in this filter but it will have to wait, i recently bought the Altair 26c (a.k.a. 2600pro) i am waiting for the camera to arrive. Wish you health and clear sky!
Great video and experiments. I have the ASI1600 and have not had that foggy dew problem yet - knock on wood - even living in CT. Someone mentioned in your comments about the rate of cooling, that might make some sense, I have my scopes stored in my astronomy shed so they are at outside temps already also I use APT which does take a while to cool the sensor. - Cheers Kurt
Thanks. Yes the 1600MM doesn't seem affected by this issue (never had a problem with ours) but the 071MC is!
@@GalacticHunter Weird problem...
Fantastic video and image! I'm a big fan of the Triad and Triad Ultra filters and regularly use them in the San Diego area. These filters offer some nice options and opportunities for imaging. I've no experience with PI but Astro Pixel Processor (APP) has specific algorithms for these types of filters allowing you to process and output the data as color, mono, Ha or OIII. Good stuff.
Regarding your 071MC Pro and the artifacts on your images. How fast did you cool the camera to the target temp? I have the same camera and have seen this as well. What I found is I was cooling the sensor to quickly. I typically run at -5 or -10 and if I make sure to cool it slowly (13min or more), I don't introduce the distortions. Cheers
Thanks Gerry! As for the issue, yes it seems like cooling it down too fast was causing the problem, we'll definitely be more careful in the future now that we know this!
I recommend using a xiaomi 360 security(infrared) camera to monitor your scope during the night, that's what I do and all movements in the yard will send you a notification :)
When I watch TV or anything else when I'm imaging I have it open on my iPad so I see everything that happens 👌
We're indeed looking at security cameras right now, we definitely need one asap!
Bruh you look fit af💪
Hi, sorry for the real late coment, had the same problem with a sensor after cleaning it, had to clean it a coulpe of times and check after each clean, the are like paths od the cloth or brush used in the sensor, I could even identify the direction of the cleaning ...
the asi071 camerar does need time to defrost, it is a well known problem but easily managed, make sure the dessicants are refreshed and in cool conditions allow it to cool down in stages. Dew heater on the camera on. Love the image
Thank you!
Hello ! The baader mpcc iii needs 55mm of distance from the t2 bottom to the camera sensor, asi 071mc has 17.5mm backfocus, so you need 37.5mm spacer !
That makes sense, thank you!
Interesting upload 👌
Thanks :)
Awesome results man, hope you two are settling in ok in your new home... The neighbour''s light next door would annoy me so much.
Thanks Noel, and yes the neighbor's light is very annoying, Maybe we'll grow a tree or something to block it lol.
How well does the triad filter work for dslr photos in the same light pollution? I have the same dslr you have.
We actually plan on trying this out soon! Just waiting for the next clear night :)
I think the Optolong L-Enhance is doing the same job for just a fraction of the price.
I'm glad you think so. I have the Optolong and it didn't feel cheap.
We've been wanting to try that filter for a while, we might borrow it from a friend and give it a try after galaxy season.
@@paulwilson8367 I have it to, as well I researched very good before purchasing it. The reports are that the difference with the Triad Ultra in performance are insignificant.
@@GalacticHunter Please do, I'm looking at buying the L-Enhance as well. I just purchased an ASI 533MC Pro with the L-Pro.
With the 071 you only need to go to -5c based on the dark noise chart aways use the anti dew
Good to know, thanks!
Would you say that this filter is alot better than the tri-band filter or about the same ?
Great!)
So since you can share raw image data in theory you could have 4 scopes on the same target each with a different filter then combine data taking far less time. Am I correct because an array would be awesome?
Imaging from home, or more appropriately a nearby park will be the only option I'll have for the forseeable future, once I get my telescope. The joys of not owning a vehicle to get around. On the flipside though, if I'm willing to walk a tad further (or I suppose just hire a ride) I can easily make it over to a nearby observatory, where one is allowed to set up their own gear in front of it, and it's reasonably dark over there since it's further away from downtown.
Sounds like you will need a pretty portable setup!
Has anyone had those strange artifacts with the ASI533 color cam?
This biggest challenge I have had with the 533 is when pointed at bright objects or if a bright star is in the frame i get reflections really bad on the sensor. At first I thought this was my image train. I took out everything and had it at prime focus and still had the really bad internal reflections. Creates a pattern of square boxes all around the bright object.
For that noise pattern are you using dithering? It help with a “ random noise” cmos have.
Yes we are
Galactic Hunter btw with that spacer how many mm did you use to get the right backfocus?
I think you need another 16.5mm?
@@davidemancini7853 We actually did not achieve the perfect backfocus since the video, we might try 22mm next time and see how it goes. In total I believe it's supposed to be 55 or 56mm.
isnt that called walking noise? happens on my dslr if i dont dither
Make sure you don't turn the cooler on first. Turn the camera on. Then set the temp to 0 with 5 min time length. Once it get to 0 then go to -5 with 5 min. Again push it to -10 with 5 min. That's it, don't try to push it down any further. Rarely I image -20 with ZWO ASI 071. BTW, great filter video and good image! I will be in Vegas not the next week but the following week for work for couple of days!
Oh wow, that is very good information to have, thank you so much! We hope you enjoy Vegas, seems like you'll be here when the moon is up :)
This looks terrific. When I got interested in astrophotography I started looking at UA-cam videos to learn more about the hobby and what equipment to buy, and I've decided to buy this exact set up you call have. I'll be buying everything on the 6th of March.
So please include a link to this filter so that I can buy it, because I'll be filming in my backyard, and I been looking for information on a light filter to pollution.
And, again, the nebula looks fantastic.
It is $400.00
@@WDE1121 actually, it a $1000. I just poked around and found it. holy moly. Well so long as it delivers good results. I'll just have to wait a few weeks before buying it.
Dang! I'd never spend 1k on a filter. That's more than most telescopes.
Check AstroBackyard Trevors UA-cam video about LR filters, I bought an IDAS LPS D2 filter based on the results shown. ua-cam.com/video/hFq-y8wTp9o/v-deo.html
Hi, the one shown in the video is the ULTRA version, which can be found here: bit.ly/31SVER0 They also have the regular Triad Tri-band which is much cheaper and still yields nice results. As for the rest of the gear you can find it here: www.galactic-hunter.com/post/our-full-astrophotography-equipment . Consider using our links for your purchases as it will help support our channel. Thanks and we hope this helps!
Looks good, but ugh. There is just no way I will ever spend 1000$+ on a filter.
The Tri-band version is $400 and is also very nice :)
@@GalacticHunter I have the tri-band filter I'm in London brotle 8 and the light pollution is really bad mate
New Home, New Filter and Good Shot
Haha thanks :)
Nice video! Thanks. But a tip for polar aligning, don’t buy a Polemaster. Completely unnecessary. Just use NINA’s 3 point polar alignment plug-in with your regular imaging camera. Works perfectly and costs nothing!
071 Users suffer from frost problems, but that is normal because the sensor is larger.
Because of the way it is cooled, and the chamber isn't sealed in a vacuum or Argon, dew or frost are likely to accumulate.
That's why zwo added the anti dew feature.
Next time just don't turn it off, if you are pushing the cooling hard.
Thank you, good to know!
0:29 looks like you have a Paramount MYT in your house!
Haha we were trying to hide it from all the camera angles, good catch.
Look like a walking noice or bayer noice to me if your test shot taken without dithering while guiding. Try to enable dithering in your guiding may solve it.
We do dither. It actually was some fog/dew on the sensor!
get a motorcycle disc lock/alarm. attach it to the tripod. someone moves the scope the alarm goes off.
👍👍
This a very expensive filter do you think it is worth the investment?
When I saw the price, I was like "holy shat"... that's expensive. I would think for them it's worth the investment. They use to have to drive out to the Nevada desert, some two hours away for them. The filter will pay for itself in the gas they can save!
Tim is right, it depends on what you usually do. I would say that for us, it is worth it. We also always think about the long term and, in this case, we would pick the Ultra over the Tri-band despite the huge price difference.
I wonder if Galactic Hunter will see this! :D #EarlySquad!
Of course
bonjour moi je la trouve pas mal au final
Oui franchement je suis impressionné du résultat !
$1,000+??? That's insane. It does a great job but still, that price is nuts.
The results are mind blowing for bortle class 9. With all the excitement when you opened the filter, were you breathing heavily? I know I would be. Maybe that's where the condensation came from. Just kidding. But maybe try removing the filter and blowing it and the sensor with a can of compressed dry air.
Awesome result. It's great being able to image from your backyard. I do most of my imaging now from it. Nothing beats a dark sky but you gotta love the convenience of the backyard. I did a video as well on this filter. You can see my result on IC1396 with and without the filter. ua-cam.com/video/Q5TMmpZYMno/v-deo.html It worked great. I found the Triad had less orange cast to it than the Optolong which was a good thing. The light pollution is a problem for sure. Maybe chat with your neighbour about shielding their lights? Invite them over to see the telescope at night and see what you do. Doesn't hurt to try!
Another comment for you. Never leave your telescope out overnight with the scope pointed towards the sky and uncovered. Best case scenario you will get some dust and dew on your primary lenses. Worst case you might accidentally leave it in a position that the scope ends up pointing at the sun at some point and you come out to a cracked primary mirror or melted mirrors/components!
House work at 3:46? Ha.
Hmmm... 0:27 i see some software bisque in the window!
Cant wait to see a video on it. =)
oh noooooo we were trying so hard to hide it in all our shots haha. Oh well. Yes, video coming at some point :)
It's a fantastic filter but the cost from OPT is astronomical, Altair Astro make a version that is way more affordable

Phew. I need a tracker first and foremost. I can take upto 13 second per image without star trails with my widest lens. That's not enough unless it's a bortle 3 or below sky.
We started out with a DSLR and Tripod without tracking and were able to get some great images of M31, M42 and others (we have a video about it) but we indeed had to travel to a Bortle 3 zone to get these. From the city it might be possible with such a filter but we haven't tried it yet!
@@GalacticHunter do you guys recommend the omegon star tracker for long term wide angle and mid telephoto(210mm with crop factor lens).
@@GalacticHunter I'm a sony a6300 user with kinda heavy lenses. Also what tripod do you guys recommend under 100usd. I would use it for general purpose and astro too
@@pupperemeritus9189 Yes and no, we reviewed it last year ( www.galactic-hunter.com/post/review_omegon_minitrack ) and liked it a lot, but if you're going to be using mostly heavy lenses in the long term, might as well get a stronger one like this one bit.ly/2QwxjfB
@@pupperemeritus9189 amzn.to/2Jh4eld This is the one we have and we're in love with it (been using it for 4+ years).
I agree that it's nice to leave the scope set up, just in case the next night is also clear. I remove the cameras also and throw a big tarp over the rig to make it less obvious what it is and keep off the dew. You probably have room now for a giant attack dog, but kitty wouldn't be thrilled.
Haha Gilbert our cat would probably not help indeed.
Lol at 8:52 who cares when you have your telescope 🤩
